USB patches for 3.10-rc1
Here's the big USB pull request for 3.10-rc1. Lots of USB patches here, the majority being USB gadget changes and USB-serial driver cleanups, the rest being ARM build fixes / cleanups, and individual driver updates. We also finally got some chipidea fixes, which have been delayed for a number of kernel releases, as the maintainer has now reappeared. All of these have been in linux-next for a while.
